Scheduling of Large Scale Power Plants in the Presence Of Electric Vehicles Considering Uncertainty Using Point Estimate Method
At present, production managers of electricity industry show high tendency to use the small generation units connected to the distribution networks and near the consumers instead of the large generation units connected to the transmission network. These small units are called Distributed Generation units. The use of the electrical vehicles will increase due to clean and cheap fuel in the future. Battery charger of these vehicles imposes charge on the power system and power plants. By controlling charge and discharging batteries, battery of these vehicles can be charged in low charge and discharged in peak charge. These power plants reduce dependency of the power system on the expensive power plants in charge peak and reduce the operation cost. The power plant unit commitment is a complex…

Remote classification of images using the new fuzzy clustering algorithm based on the weight
Fuzzy clustering model is an essential tool to find the proper cluster structure of given data sets in pattern and image classification. In this paper, a new weighted fuzzy C-Means (NW-FCM) algorithm is proposed to improve the performance of NW-FCM models for high-dimensional multiclass pattern recognition problems and its result has been compared with the results of FCM, NFCC, and NW-FCM fuzzy clustering algorithm. The methodology used in NW-FCM is the concept of weighted mean from the nonparametric weighted feature extraction (NWFE) and cluster mean from discriminant analysis feature extraction (DAFE). These two concepts are combined in NW-FCM for unsupervised clustering. The main feature of this algorithm comparing the other three one includes the weight mean for increasing the…

DSA Generation using Micro Ring Resonators
A novel system of dark soliton array (DSA) for secured communicationgenerated by using the multiplexed dark soliton pulses is proposed.Different wavelength of soliton pulses with relevant parameters areinput into the micro ring resonators system with the radii of 7 μm and2.5 μm, where the dynamic dark solitons can be generated. The DSAare obtained by using a series micro ring resonators with parameterswhere in the wavelength range of λ1 is 1516 nm , λ2 is 1518 nm and λ3is 1520 nm. For security applications, the DSA can be tuned andamplified. Thus, the use of DSA for high capacity and capacity can berealized by using proposed secured system. In transmission, the longdistance link of the multi variable network can be performed by thisDSA….

Voltage Effect on the Optical Properties of Liquid Photonic Crystal Fiber
The parametric performance of the photonic crystal fiber (PCF) infiltrated by LC 5CB is studied under the voltage variations. The COMSOL and MATLAB softwares have been used to study the performance of PCF under the variations of optical parameters including the effective refractive index, the normalized frequency, the effective mode area, numerical aperture and waveguide dispersion. Results indicated that both single-mode transmission and ultra-flat dispersion can be achieved under the appropriate voltage and geometric structure. Moreover, stable nonlinear effect is appeared at air holes with a large radii. It provides references to design a device for sensing applications in terahertz regime….

A Compact Monople UWB Antenna With Inverted D-Shape Slots For Band Rejection
A compact monopole microstrip notched ultrawideband (UWB) with rotated D-shape slots in the patch is presented. By introducing a new inverted D-shaped notch in the radiating plane, band-notch which is about 5.14 to 6 GHz and 6.21 to 8.66 GHz and 6.21 to 8.66 GHz are achieved. The proposed antenna offers 127% bandwidth overall dimension of 13×17×1.6 mm3. The experiment results demonstrate that the proposed antenna can well meet the requirement for the UWB communication in spite of its compactness and small size. VSWR is nearly under 2 which are very good for wireless application. The characteristics of compact size, low profile, and simple structure make the proposed antenna suitable to use for the UWB wireless communication applications….

Getting top management in a company to approve investments in Big Data and is related investments
This year begins the shift of big data away from a topic unto itself, and toward standard practices, said Nick Heudecker, research director at Gartner. The topics that formerly defined big data, such as massive data volumes, disparate data sources and new technologies are becoming familiar as big data solutions become mainstream. For example, among companies that have invested in big data technology, 70 percent are analyzing or planning to analyze location data, and 64 percent are analyzing or planning to analyze free-form text….
